In this study adults performed numerical and physical size judgments on a symbolic (Arabic numerals) and non-symbolic (groups of dots) size congruity task. The outcomes would reveal whether a size congruity effect (SCE) can be obtained irrespective of notation. Subsequently, 5-year-old children performed a physical size judgment on both tasks. The outcomes will give a better insight in the ability of 5-year-olds to automatically process symbolic and non-symbolic numerosities. Adult performance on the symbolic and non-symbolic size congruity tasks revealed a SCE for numerical and physical size judgments, indicating that the non-symbolic size congruity task is a valid indicator for automatic processing of non-symbolic numerosities. Physical size judgments on both tasks by children revealed a SCE only for non-symbolic notation, indicating that the lack of a symbolic SCE is not related to the mathematical or cognitive abilities required for the task but instead to an immature association between the number symbol and its meaning.
在本研究中，成年人对一个符号（阿拉伯数字）和非符号（点组）大小一致性任务进行了数字和物理大小判断。结果将揭示无论符号表示如何，是否都能获得大小一致性效应（SCE）。随后，5岁儿童对这两项任务都进行了物理大小判断。结果将更深入地了解5岁儿童自动处理符号和非符号数字量的能力。成年人在符号和非符号大小一致性任务上的表现显示，在数字和物理大小判断方面存在SCE，这表明非符号大小一致性任务是自动处理非符号数字量的有效指标。儿童对这两项任务的物理大小判断仅在非符号表示法中显示出SCE，这表明缺乏符号SCE与任务所需的数学或认知能力无关，而是与数字符号与其含义之间不成熟的关联有关。
